[erlang-questions] Return status of gen_udp send

Tim, you are correct about the 'fire and forget', but that is only for
the part outside your own machine.
The original poster wanted to know if the message really got sent or got
dropped in his own machine.
Which actually poses a question in my head: what does it matter where
the message was lost?
The only reason I can think of right now is to control load on your own
kernel and slow down if you are pushing your machine too hard.
Perhaps the original poster can clarify?
